ARTHUR HAMMOND SHIPLEY, OF LEICESTER, ENGLAND, ASSIGNOR TO WESTON,SHIPLEY & WESTON, LIMITED, 0F LEICESTER, ENGLAND.

MACHINE FOR INSERTING LACING-STUDS.

Application filed October 20,

b all whom it may concern Be it known that I, ARTHUR HAMMOND RHIPLEY, asubject of the King of Great Britain, residing at Leicester, in thecounty of Leicester, England, have invented new and useful Improvementsin Machines for Inserting Lacing-Studs, of which the following is aspecification.

This invention relates to a machine for inserting what are known aslacing studs into material such for example as the uppers of boots andshoes.

The object of the invention is to produce a machine which willautomatically insert fasteners of the known type comprising a stud orshank portion and a button or head port-ion, the two parts being broughttogether on opposite sides of the material and then clenched 0r pressedtogether to permanently unite them.

The two portions of the fasteners will be hereinafter referred to as thestud and butrately contained in two hoppers or pouches on the machine.

An important feature of the invention is that the fasteners are insertedinto the material with the button portion uppermost, the outside of thematerial being upwardly disposed and thereby presenting the right sideto the view of the operator. The material is previously perforated forthe reception of presents each hole in the material and dethe machinemakes one revolution and auto matically inserts a fastener.

The stud parts are lifted from their respective hoppers by means ofrotary elevators and are thereby delivered to chutes mechanism.

Each chute has a separating or escapement device to deliver therespective fastener parts one at a time to the inserting mechanism;

and hold the stud part, and a presser rod furnished with movable jaws toreceive and hold the button part and adapted to place it in positionupon the stud and afterward clench it thereon.

The stud parts are fed into position stem upward andthe button parts arefed into position over the stud parts with their Specification ofLetters Eatent.

shanks downward so that the material may be presented to the machineface upward to receive the lacing studs.

The invention will be hereinafter further described with reference tothe accompanying drawings, wherein Figure 1 is a sectional sideelevation of one form of the machine. Fig. 1 is a front elevation of themachine. Fig. 2 is a plan view the top portion of the machine beingremoved. Fig. 3 shows an elevator removed from one of the hoppers. Fig.i is a side view of the button pouch or hopper and chute. Fig. 5 is asimilar view showing the stud hopper and chute. Fig. 6 is a plan ofsmaller scale and Figs. 6 to 9 to a larger scale than Figs. 2 to 5.

Like parts are designated by the same reference characters throughoutthe drawings.

In the machine of the drawings, '1 is the frame in and on which thevarious mechanisms are mounted, said mechanism comprising principally abutton pouch or hopper 2, a stud pouch or hopper 3, a button chute 4,

stud chute 5, a presser rod 6 for the button parts, and a die rod 7 forthe stud parts.

All the mechanisms of the machine are actuated by suitable intermediateconnections or means from a shaft 8 which latter is suitablydrivenpreferably by power.

Combined with each pouch or hopper 2 and 3 is a rotary elevator 9 and 10respectively which separates the parts contained within the hoppers anddelivers said parts to the respective chutes 4 and 5 as will behereinafter described. The said rotary elevators 9 and 10 are in theform of circular caps or flanged plates (Fig. 2) and are arrangedagainst the open sides of the pouches or hoppers so that the fastenerparts collect on the inside of the caps.

The caps or elevators are arranged vertically and the fastener partsaccumulate on the interior of the flanged portions 11 of the elevatorswhich flanges are furnished with holes 12 therein (Fig. 2) into whichthe fastener parts fall so as to be carried around by the flange 11 anddelivered to the chutes as shown in Figs. 4 and 5.

In the case of the stud portions a of the fasteners, the naturalposition for these to fall in is with their stem upward and when they sofall into the holes 12 (Fig. 5) they are carried around by the elevator10 and are delivered in the same position to the shoot 5 down which theypass by gravity. The stud portions (4 which do not correctly enter theholes 12 in the elevator 10 are either discharged back into the hopper 3or, if they are carried to the chute, they do not enter the mouth of thechute but accumulate there until they are forcibly removed by means of atransversely movable clearer 13 pivoted at l-l and which is periodically moved across the mouth of the chute by earns 15 (Fig. 2) onthe rotary elevator which cams operate a lever 16 adapted to transmitmovement to the clearer 13 through the medium of a rack 17 and pinion18. The clearer 13 swings around, as indicated by the arrow, for thepurpose of removing wrongly positioned or accumulated stud portionswhich latter are thereby swept back into the hopper 3.

The flange 11 of the elevator 10 rotates within an outer stationary Wall19 between which and the exterior of the said flange the heads of studportions a become located (as shown in Fig. while the latter are beingcarried around by the elevator to the mouth of the chute 5.

The elevator 9 of the button portion hopper operates in a manner similarto that of the stud portion elevator 10 just described. That is to say,the natural position for the button portions Z) to fall in is head downward as shown in Fig. 4, and therefore the bulk of the button portions 6resting on the exterior of the flange 11 of the rotary elevator fallinto the holes 12 in this posi tion and are consequently carried aroundby the elevator to the chute 1 the heads of the button parts beinglocated between the flange 11 and a fixed outer wall 19 (Fig' 4c). Thebutton portions which do not correctly enter the holes 12 fall out againduring the rotation of the elevator 9 and thus return to the pouch orhopper 2. Those parts Z) which do enter the holes properly however, arecarried around by the elevator, as shown in Fig. 4, and are delivered,head uppermost, to a guideway 20 (Figs. 2 and 1) which leads to thebutton chute 4, the said parts being lifted onto the guideway by acurved plate 21 (Fig. 4:) over which they ride as they are carriedaround by the flange 11 of the elevator. In this guideway 20 is a bridge22 which is periodically reciprocated or moved transversely to and froby means of cause 15 on the elevator 9 (Fig. 3). The bridge 22 isactuated from the cams 15 through the medium of a lever 16, a rack 23and pinion 24L (Fig. 2) and said bridge forms one side of the guidewayalong which the buttons must pass to the chute 1. hen the button chute 4is fully loaded with button portions 7). any accumulation of the saidparts I) at the mouth of the chute is prevented by the moving bridge 22which, upon being moved transversely allows the surplus button parts tofall back into the hopper 2.

The elevators 9 and 10 are preferably driven in unison but in oppositedirections from the same gearing 25 which latter may be driven by chainand chain wheels or in any other manner from the main shaft 8 of themachine. The holes 12 in the flanges 11 of the elevators may, ifdesired, be recessed on the rear side to receive the stems of the studand button portions so that the heads of said portions may rest againstthe outside of the flanges and prevent the parts falling out of theholes back into the interior of the elevators.

The chute 5 for the stud portions a of the fasteners leads down to thelocality of the die rod 7 which has a vertical movement in a bearing 26located in the front of the machine frame 1 and is furnished at itsupper end with a point or pin 27 on which the stud portion a of thefastener is received and held.

The up and down movements are imparted to the die rod 7 by a cam 28 onthe shaft 8 which cam operates through levers 29 and 30 (Fig. 1) orother suitable mechanism to move said rod. To receive a stud a, the dierod 7 is drawn down below the end of the stud chute as shown in Fig. 5,and when a stud falls from said chute it falls down the bearing 26 andonto the spike or pin 27 on the lowered rod 7 which latter is thereuponraised and carries the stud a to a position above the chute as shown inFig. 7, and is held there ready for the perforated material 31 to beplaced upon the upstanding stem of the stud.

The chute 4 for the button portions 6 of the fasteners leads down intoclose proximity to the end of the presser rod 6 which latter is movableup and down in a bearing 32 in the framing 1 and is immediately in linewith the before mentioned die rod 7. This presser rod consists of twoparts, an inner rod or presser proper, and an outer sleeve 6. The innerrod 33 is connected by a suitable arrangement of levers 34, 35 and 36and a link 37 with a cam 38 on the shaft 8 which cam imparts areciprocating movement to the rod 33 within the sleeve 6 and also,indirectly, an up and down movement to the latter in the bearing 32.

The movement of the outer sleeve 6 within its bearing 32 is frictionallyrestricted by means of an adjustable spring pressed pin 39 (Fig. 7located in a screw 40 and said sleeve carries at its lower end twopivoted jaws or claws 41, 41 which have inwardly bent ends 42 (Figs. 6and 7.) The jaws 41 are arranged on pivot pins 43 so as to be capable ofbeing rocked in the sleeve and when so actuated the bent ends 42 movetoward and from each other underneath the end of the presser rod, aswill be seen by reference to Figs. 7 and 9.

The opening and closing movement is imparted to the jaws 41, and alsothe up and down movement is directly imparted to the sleeve 6, by theinner presser rod 33 which latter has a recessed or cam surface 44engaged by feet 45 on the upper inner ends of the jaws 41 (Fig. 7) whilea shoulder 46 on the presser rod 33 may engage the sleeve 6 to actuatethe latter in a downward direc tion within its bearing and the end of aslot 47 in the rod 33 may engage a pin 48 in the sleeve 6 to move thelatter upward.

From the foregoing description and upon reference to Fig. 7 it will beseen that the inner presser rod 33 has a limited free movement withinthe sleeve 6 and the formation and arrangement of the cam surface 44 andfeet 45 are such that an upward movement of the inner rod within thesleeve will open the jaws 41, while a downward movement of said innerrod will close said jaws.

During the upward and downward movements of the inner rod 33 within thesleeve 6 the latter is held stationary by the pressure of the frictionpin 39, but upon the inner rod reaching the limit of its free movementin either direction (the limit being caused by the shoulder 46 or slotend 47) its continued movement causes a bodily movement of the sleeve 6so that at each re ciprocation of the inner rod 33, the outer sleeve 6travels in company with the said inner rod for a certain distance.

The length of the cam surface 44 on the rod 33 is such that after thesaid rod has closed the jaws 41 it may move farther downward in thesleeve 6. This provides that the inner presser rod may, after a buttonpart b has been received on the jaws 41, descend to hold the head of thebutton between its concaved end 49 and said jaws as shown in Fig. 8.

The bent ends 42 of the jaws 41 when in the closed position (see Figs. 4and 6) receive a button Z) from the chute 4 and are adapted to supportsaid button under the head thereof as shown in Fig. 7. The button b maymerely rest upon the bent ends 42 of the jaws 41 or its shank may begripped between said jaws if desired.

After receiving a button, the presser rod 33, sleeve 6 and jaws 41 movedownward carrying the button therewith and position the latter on thestud a as shown in Fig. 8, and the presser rod 33 clenches the two partsa and 7) together. It will be understood that before the two parts ofthe fas- 33. It might however be so arranged that the die rod 7 shouldhave a slight rising movement to meet thev opposing downward movement ofthe presser rod during the clenching operation to facilitate the latter.Or further, the presser rod might descend to bring the button part intorelative position on the stud and then remain stationary while the dierod rose to clench the two parts together.

After clenching the parts a and b the inner presser rod 33 rises andbefore imparting any rising movement to the sleeve 6 and jaws 41, itopens the latter so that they move away from the button I) as showninFig. 9 and can rise clear of it. After rising and returning the sleeve6 to its normal raised position, the inner rod 33 moves downward againfor a short distance to close the aws 41 or move them toward each otherpreparatory to their receiving another button from the chute 4.

The main shaft 8 of the machine is driven, preferably from acontinuously running pulley (not shown) by means of any suitable form ofsingle cycle clutch mechanism brought into operation by the depressionof a treadle 50 (Fig. 1) or the actuation of an equivalent member.

The chutes 4 and 5 and hoppers 2 and 3 are, as shown in Fig. 2, arrangedon opposite sides of the machine and each chute is furnished with anescapement or separating device which allows only one stud a and buttonpart b at a time to pass to the die rod 7 and jaws 41. This device mayconveniently consist of a rotary disk 51 which intercepts the passage ofthe parts down the chute. The said disk 51 has a recess or curvedopening 52 in one side and this recess, each time the disk rotates oroscillates, passes one of the parts, i. 6. it receives a part thereinand transmits it on along the chute to be delivered.

The disks 5.1 may be toothed and be actuated by racks 53 from the cams15 on the rotary elevators 9 and 10 or they may be actuated by any othersuitable mechanism.

The machine of this invention, instead of being employed forautomatically inserting and fixing two part lacing studs as hereinbeforedescribed, may be used for automati- (ally insert-ing and fixing lacingstuds or similanarticles which consist of but a single member. such forexample as a button member adapted to be attached by clenching orbending out its shank after the mannet" of an eyelet. lVhen so used thepresent machine may comprise but a single hopper and chute such forexample as the hopper 2 and chute 4-. and the die rod 7 instead of beingmovable would be stationary, unless it is desired to use the up and downmovement of the press-er rod merely for the purpose of positioning thefastening in which case an up ard movement of the die rod would berequired to clench or expand the fastening in the material.

What I claim then is:

In a machine for inserting the button part of lacing studs, means forreceiving and setting the button part, consisting of an outer sleevehaving africtionally restricted sliding movement an inner presser rodhaving a limited longitudinal movement within the sleeve, pivoted jawsin the end of the sleeve, inwardly bent ends on said jaws to receive thebutton part and support it under the end of the presser rod, feet onsaid jaws, a cam surface on the inner presser rod engaging the feet onthe jaws and respectively opening and closing said jaws upon an upwardand downward movement of the said rod taking place within the sleeve,and means to actuate the said rod, the latter imparting a bodilymovement to the sleeve upon reaching the limit of its free movementwithin the sleeve in either direction, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
